Lumbar intervertebral disc herniation is one of the more common disorders, mainly because after degenerative changes of different degrees in the components of the lumbar intervertebral disc, under the action of external factors, the nucleus pulposus tissue protrudes (or prolapses) from the rupture of the annulus fibrosus in the posterior or spinal canal, resulting in the adjacent spinal nerve roots suffering from irritation or compression, resulting in a series of clinical symptoms such as lumbar pain and numbness and pain in the lower limbs, which seriously affects The quality of life of patients is seriously affected. Prior to the advent of interventional disc therapy, open surgery was the only effective means of treating severe disc herniation. Interventional therapy has introduced a minimally invasive concept to the treatment of herniated discs. The currently available interventional methods include collagenase lysis, percutaneous excision and suction, laser vaporization (PLDD), plasma pulpal nucleoplasty, ozone, and radiofrequency ablation. However, all the above methods are indirect decompression, only for some cases of inclusive protrusion, and cannot completely remove the diseased nucleus pulposus, especially the tissue compressing the nerve root, and cannot repair the broken fiber ring, and the necrotic tissue needs to be absorbed by the body naturally, which is long, painful and has a high recurrence rate. The development of posterior discoscopy in the mid-1990s advanced the concept of minimally invasive surgery one step forward, and the majority of orthopedic surgeons gradually realized that with the emergence of new technologies and materials, minimally invasive techniques were bound to be the direction of development of surgery. The initial posterior discoscopy (MED) technology is not fully mature, its surgical access and treatment process are consistent with small incision open surgery, both have to implement the vertebral plate opening, stripping muscles and ligaments, disturbing the spinal canal and pulling the nerve (to a lesser extent than open surgery); it is easy to cause intraoperative bleeding, interfere with the visual field and increase the risk; it cannot be applied to the treatment of extreme lateral type herniation and discogenic pain; postoperative scar tissue It is not a perfect minimally invasive surgical technique because of its tendency to cause adhesions to the spinal canal and nerves. The newly emerged “intervertebral foraminoscopy technique” overcomes many of the shortcomings of discoscopy and is the most minimally invasive, safe and economical technique, pushing the minimally invasive treatment of disc herniation to a whole new level. In addition, the technology is rapidly evolving and is now being used in new areas such as artificial disc and nucleus pulposus replacement, foraminoscopic fusion, percutaneous techniques for internal fixation, minimally invasive treatment of spinal tuberculosis, and minimally invasive treatment of cervical foraminoscopy, with its excellent clinical efficacy and significant academic value attracting more and more orthopedic surgeons to focus on this technology. The THESSYS minimally invasive foraminoscopic spine technique is a well-established and mature technique, developed by the renowned German spine surgeon Thomas Hoogland. Hoogland and others have performed more than a thousand successful procedures before it was introduced to the world. The main advantages of the technique are as follows: i. Less anesthesia interference, when the situation allows, the patient can undergo surgery under local anesthesia, be completely awake during the operation, and be able to communicate with the surgeon at any time during the operation. The technique can remove the herniated or prolapsed nucleus pulposus without removing the intervertebral ligaments, vertebral body or intervertebral joints, or cutting the trunk muscles, with little interference with the stability of the spine. The patient can be discharged from the hospital in 2-3 days, and can return to normal life and work very quickly. The published international literature reports a success rate of over 90% in the application of minimally invasive laminectomy techniques with a better outcome and an early recurrence rate of less than 5% at 1 and 2 years postoperative follow-up. In patients with recurrence, the success rate exceeded 84%. This technique represents a new minimally invasive surgical concept that allows for herniated discs, foraminoplasty and annulus fibrosus repair in all segments from cervical to lumbar 5-sacral 1. It is now internationally recognized that laminectomy will dominate the field of spine surgery in the future. For the treatment of lumbar disc herniation, traditional open surgical treatment options are more traumatic, have a greater impact on the structure of the spine, are relatively expensive, have more complications, and involve long bed rest, which patients are generally unwilling to accept. Conservative treatment options such as massage and physiotherapy have unclear efficacy, cannot eradicate the cause of the disease, recurrence of the disease, and sometimes even delayed treatment leads to aggravation of the original condition, and is not the best solution. Minimally invasive intervertebral foraminoscopic surgery technology is a new recommended surgical option with minimal trauma, low infection rate, clear results and fast recovery, which meets the various needs of patients. In order to solve the long-term pain of the majority of lumbar disc herniation patients, our hospital took the lead in carrying out foraminoscopic herniated nucleus pulposus removal in Zhenjiang City and achieved success. The operation only requires a “keyhole-sized” incision in the patient’s lumbar back to solve the back and leg pain that has plagued them for many years and improve their quality of life, with remarkable results and fast recovery after the operation.
